Class FieldQParserPlugin

Create a field query from the input value, applying text analysis and constructing a phrase query if appropriate.
Other parameters: f, the field
Example: {!field f=myfield}Foo Bar creates a phrase query with "foo" followed by "bar"
if the analyzer for myfield is a text field with an analyzer that splits on whitespace and lowercases terms.
This is generally equivalent to the Lucene query parser expression myfield:"Foo Bar"
